If we can hold our wild conspiracy theories for just a second and actually read the article.
The software is all about passenger movements and behaviours. For example person A enters the station from point X and tops up myki, checks display boards, walks to the platform, and so on. This is essentially movement data and something that PTV/DoT should have been doing long ago.
How does the average commuter use the station, is there a pinch point, is one entrance more used than another; this all feeds into how new stations should be designed and existing stations modified to better manage increasing passenger numbers.
CCTV cameras are installed across the network already, the inner core would have thousands of them. This software just makes them 'smart'. The software identifies and gives a person a marker, it can then track you across the different cameras across the station essentially drawing a map of how you used the station. You layer the thousands of people that use a station every day and you can start to see movement trends as I've described above.
It's similar for level crossings, it can track how a person uses these and trespasses, giving data on how to prevent this from happening.
This kind of software is widely used around the world in metro systems and urban cities, we are just 20 years behind.
